Is this the correct book for small blocks?

The BEST book on rebuilding is the Factory Service Manual.
The others all have some value as far as tricks or interchangeability between years, but the first book you should always buy (or download, if that is your preference) is the FSM.

I do have the year-specific FSM, but wondering if something like this would be useful, and you've pretty much answered. :)

Much appreciated!
